Wolfe's Den 7/29/2011 123 comments Lighter automotive materials and hybrid engines are two engineering approaches towards meeting the Obama administration's goal of 54.5 mpg CAFE standards for automakers by 2025.
Embedded Multicore Goes Mainstream
Blog 7/26/2011 4 comments Multicore designs of four or more processors on a single chip are cheap enough for embedded and industrial applications, but not all multicore processors are appropriate for the task.
Design Apps Hit the iPad
CAD/CAM Corner 7/25/2011 10 comments While we're starting to see a steady stream of design-oriented apps for the iPad and other mobile devices, the majority remain focused on simple viewing and collaboration functions.
Convert Garbage to Electricity at Home
Gadget Freak 7/22/2011 8 comments Trevor Nestor built a gasifier out of some steel cans and camping pans. The basic idea of a gasifier is that you burn wood, trash, or other unwanted organic items in an environment low on oxygen.

3D Printer Kit Ordering Woes
Blog 7/21/2011 6 comments Guest blogger and additive manufacturing maven Todd Grimm describes the sometimes frustrating process of ordering a kit to produce three-dimensional parts from common plastics.
Old Tires & Soy Seed Ford's Gaskets
Engineering Materials 7/20/2011 7 comments Ford continues its leadership in development of natural automotive materials with use of recycled tires and soy oil to make seals and engine gaskets.
Terrafugia Transition Inches Closer to Flight
CAD/CAM Corner 7/18/2011 17 comments The so-called flying car reached another milestone, having been granted key exemptions by government safety agencies that were critical due to the engineering challenges around a dual-purpose design.
The Case of the Jumping Gyro
Sherlock Ohms 7/14/2011 4 comments A remote-controlled underwater vehicle had a heading servo referenced to a gas-rate gyro, which had a trimmable dc offset. Every once in a while, the heading took a jump of 10 to 15 degrees.
ANSYS Acquires Apache Design Solutions
CAD/CAM Corner 7/14/2011 2 comments With its $310 million acquisition of Apache Design Solutions, ANSYS is poised to deliver more of a systems-level approach to integrated circuit design, delivering simulation capabilities from initial IC prototyping to system signoff and design.
Final Shuttle Flight Creates Opportunity
Guest Blogs 7/13/2011 13 comments Watching the space shuttle Atlantis take flight invoked a sense of optimism that it opens up an opportunity to build even better spacecraft that are more affordable, better integrated, better manufactured, and better supported.
CATIA Revision Supports Functional Mockups
CAD/CAM Corner 7/12/2011 2 comments New systems engineering functions in CATIA V6R2012, along with a partnership with aerospace giants EADS and Astrium, are propelling Dassault Systèmes's emerging vision of a Functional Digital Mock-Up (FDMU).
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
